BARRIERTA KM 192

BARRIERTA is Europe's oldest high-quality brand of hightemperature lubricants based on perfluorinated polyether oil (PFPE). Today the name of BARRIERTA is widely regarded as synonymous with long-term stability and thermal resistance. BARRIERTA greases are the first choice of lubrication experts in many sectors worldwide. BARRIERTA K greases enable long-term use under high temperatures and influence of media, while at the same time requiring low running torques at low temperatures. This was made possible by Klüber's careful selection of raw materials and the specifically developed thickener.

Rolling bearings and guideways
BARRIERTA K greases are highly suitable for the long-term lubrication of rolling and plain bearings, where only low driving power is available and where long-term stability is required under changing environmental loads. Even at extremely low temperatures, BARRIERTA K greases are soft enough so as not to overload lowpower drive units, while on the other hand they withstand temperatures as high as 200°C and beyond. BARRIERTA K greases are used for a wide range of applications as for-life lubricants in automotive, electrical and precision engineering.
Valves and seals
The BARRIERTA K greases good temperature resistance and their compatibility with plastics and elastomers – which is typical of PFPE lubricants – make them highly suitable for the lubrication of enginevalves and seals as are found in hydraulic cylinders. BARRIERTA KM greases enable long runtimes with low noise generation and low friction coefficients. The resistance of BARRIERTA KM 192 against brake fluids, type DOT 3, 4, 5 and 5.1, has been confirmed in an individual test.
Compatibility with elastomers and plastics
BARRIERTA K grease stand out for their neutral behaviour towards elastomers and plastics. Owing to the many different varieties of elastomers and plastics and varying operating conditions, we recommend checking their compatibility with the component material prior to series application.

Long component life

over a wide service temperature range
when exposed to aggressive chemical agents
due to a long calculated grease life

Improved component performance

due to low starting torques even at low temperatures
due to resistance to high speeds
due to friction values being largely independent of temperature
